Smoke from lead bullets??

[Skip Sackett]

Just by way of information, Precision still recognizes that there may be some issues with their bullets too.
Some excerpts from their website:

RELOADING INFO
Any powders for cast lead bullets will work for Precision Bullets.
Recommended Powders
Vihtavuori – N-320/N-340
Ramshot – Competition/Zip
Winchester – WST
Alliant – American Select/Power Pistol
Hodgdon – Universal Clays/HP38

Not Recommended Powders
Hodgdon – Titegroup
Vihtavuori – N-310

Note: If you are having a fouling problem or too much smoke, try a little slower powder.

RELOADING TIPS
Make sure to have a good bell on the case so not to shave off the coating during the seating process.
Do not seat and crimp the bullets in the same die. Use a separate taper crimp die.
We highly recommend Dillon reloading equipment.
Do not use a roll crimp or Lee Factory Taper Crimp Dies.
The roll crimp will cut through the coating. You must use a taper crimp die.
The Lee Factory Taper Crimp Die will undersize the bullets causing accuracy and fouling problems.
Most of the time a heavier crimp will work better.

TROUBLESHOOTING
Too much smoke and fouling
Make sure you have a good bell on the case and not shaving through the coating during the seating process.
If you are using brand new brass, make sure there is not a sharp edge on the inside of the case mouth (try used brass).
Make sure you have a good crimp.
If you are using the Lee Factory Taper Crimp Die, try switching to a standard taper crimp die.
If you are seating and crimping in the same die, try switching to a separate seater and taper die.
Try a slower powder.
Slug your bore, oversized bores will foul heavily and be inaccurate.

CLEANING YOUR BORE
Normal cleaning methods will work for our bullets, but sometimes the coating will stay in the barrel. If you cannot remove the coating with traditional cleaners—Shooter’s Choice, Breakfree, etc.—see methods below.
Stainless steel barrels only
50/50 mixture of hydrogen peroxide and vinegar in a jar
Make a hook out of a paper clip
Remove barrel and lower into mixture with paper clip hook
Soak for 20 minutes
Remove barrel and wipe off excess with paper towel
1 pass with a bore brush
1 pass with a tight patch
Flush out under sink with water
Dry off, patch out, and oil
Carbon steel barrels
Take a “Chore Boy” stainless steel scrubbing pad
Cut off a spiral portion from the pad
Wrap around brass cleaning brush
Apply Breakfree CLP—5 or 6 passes through the bore
Patch out with favorite cleaner
Dry the bore and oil

Before I would use these bullets, even though the cost is about 1/3 more, I would rather use plated ones. They are available from more than one source, stocked locally, clean up is a breeze.

It is always good to examine both sides of the coin when attempting something new. To quote a friend of mine; "It's a mighty thin coin that ain't got two sides!"
